WATER-CLOSET FLUSHING APPARATUS.

SPECIFICATION formingpart of Letters Patent No. 668,999, dated February26, 1901. Application filed May 29, 1900. Serial No. 18,427. the model.)

To all whom, it may concern:

Be it known that 1, WILLIAM H. OSBORN, a citizen of the United States,residing at Louisville, in the county of Jefferson and State ofKentucky, have invented new and useful-Improvements in ater-ClosetFlushing Appathe following is a specification.

My invention relates to Water-closet flushing apparatus; and the objectsof the same are to provide simple, eficient, and reliable means forflushing the closet automatically after the same has been used and toalso provide automatic means for refilling the bowl after the flushingoperation has been effected.

Another object of my invention is to provide means operated by a hingedseat for the closet which will cut off the water-supply when weight isapplied to the seat and which will open the valves when the Weight isremoved to both flush the closet and refill it.

I attain these objects by means of the construction shown in theaccompanying drawings, which form a part of this specification, and inwhich- Figure 1 is a perspective view of a watercloset made inaccordance with my invention. Fig. 2is a side view of the same. Fig. 3is a plan view of the apparatus in the water-tank, the cover of whichhas been removed to more fully illustrate the interior mechanism. Fig. 1is a side view of the flushing-valve. Fig. 5 is a central verticalsection through said valve and valve-seat. Fig. 6 is a sectional viewthrough the tank. Fig. 7 is a plan view of the mechanism for operatingthe flushingvalve. Fig. 8 is aplan view of the under side of the seat,showing the hinge and the lever for operating it.

Like numerals of reference designate like parts wherever they occur inthe different views.

In said drawings the numeral 1 designates a water-closet bowl of anysuitable or preferred construction and 2 is a water-tank of the usualform and of any desired capacity. The seat 3 for the bowl is providedwith a hinge consisting of a plate 4., secured to the under side at therear of said seat, said plate having four lugs 5, provided with alinedperforations 6 for the pintle-rod 7, which connects the seat to the lugs8, formed on a plate 9, rigidly secured to the bottom of the watertank2. The plate Lhasa projecting portion 10, which forms a bearing-surfacefor an antifriction Wheel or roller 11, journaled in the upturned end ofalever12, pivoted to an arm or bracket 13, rigidly secured to the bottomand front side of the tank. The lever 12 is provided with alateral arm14, eXten dingoutward from its rear end, and a rod ext-ends through thisarm and is secured in place therein by lock-nuts 16, fitted to said rodat the top and bottom of said arm. Another rod 17 is secured to the arm14 by lock-nuts 18, and by means of these lock-nuts the rods 15 and 17may be adjusted to regulate the leverage necessary to properly operatethe flush-valve. The rod 15 extends up at the side of the tank and isheld in place by a guide or keeper 19, secured to a wear-plate 20,attached to the side of the tank. At the upper end of rod 15 a weightedtrip 21 is pivoted, this trip having a rounded end 22 and a weight 23 atthe opposite end. A lever 24. is pivoted to the wear-plate at 25 and hasa hooked arm 26, which normally lies in the path of the trip 21, and anarm 27 is pivotally connected to a vertical rod 28, which extendsthrough a keeper or guide 29, secured to the tank. The upper end of rod28 is connected to the arm 30 of a rock-shaft 31, journaled in keepers32 on the tank and having an arm 33, terminating in a loop 34:. I Abolt35 is seated in this loop and provided at its upper end with anadjusting-nut 36 for the links 37 of a chain connected at one end to thenut and at the opposite end to an inverted cup-valve 38. This valveconsists of a hollow sheet-copper shell, having a flange 39 at its openend, and a rubber gasket 40 seated behind the flange 39, said gaskethaving an outwardly-flaring seating-surface designed to form awatertight joint when it rests upon the valve-seat 41 at the upper endof the flushing-pipe 42, which connects with the closet. An L-shapedoverflow-pipe 43 connects with the flushing pipe 42, immediately underthe valve-seat 41. Surrounding the upright portion of the pipe 42 is acollar-clamp 4.4, which is adjustably secured to the pipe 4.3 by thescrew 45. Formed on the clamp 44 is a lug 46, having an aperture 4E7,which forms a pivot-bearing for a wire bailor lever 48, the opposite endof said bail being attached to the valve-cup 38 at its upper end. Theclamp 44 is adjustable on the overflow-pipe 43 to change the fulcrumofsaid closet.

point of the bail or lever 48.

The vertical rod 17 extends up through the bottom of the tank and into aseparate apartment 49 in said tank. A spring-buffer 5O surrounds the rod17, and a weight 51 is attached to the upper end of said rod.

A small L-shaped pipe 52 is connected by its horizontal member 53 to thelower portion of the overflow-pipe 43. The vertical member 54 of thepipe 52 has secured near its upper end a clamp similar to 44, having anadjusting-screw 55 and an upwardly-curved arm 56. Pivoted to the arm 56is valve-lever 57, havinga valve 58 at one end thereof, said valveadapted to rest upon the seat 59 to form a water-tight joint. Theopposite end of the valve-lever 57 is provided with an upright rod 60,said rod being threaded at 61 near its upper end to accommodate anadjustable float 62, which may be a hollow copper ball having a centralthreaded tube 63 passing through it.

An ordinary ball-float 64, connected up in the usual manner to asupply-cock 65, may be used in connection with my apparatus.

It will be noticed that my apparatus is operated entirely from the seat3, and for this reason my improvements may be applied to any closet-bowlwithout change in structure It will also be obvious that in my apparatusthere are no unsightly and cumbersome weights and other mechanism infull view about the seat.

The operation of my invention is as follows: The seat 3 when not in useisheld slightly elevated at its front portion by the roller 11 on thelever 12. WVhen the seat is depressed by the weight of a person upon it,the lever 12 is elevated at its rear end, thus raising the rod 17 andits weight 51 and also pushing the rod 15 upward to permit theflush-valve 38 to fall upon its seat and arrest the flushing mechanism.When the person arises from the seat 3, the weight 51 will fall upon thespring-buffer, so as to be noiseless, and will operate the lever 12 topull down the Weighted trip 21 to move the lever 24 and through theconnections 27, 28, 31, and 37 raise the flushing-valve 38 to flush thecloset. When the trip :31 has passed the hooked arm 26 of the lever 24,the cup-valve 38 will fall on its seat 41 and shut off theflushing-stream. The water in the tank will at this time be sufficientlylow to open the valve 58 to refill the bowl through pipe 52, and thestream will continue until said valve is closed by its adjustable float.

I am aware that changes in detail may be resorted to Without departingfrom the spirit and scope of my invention. I do not, therefore, desireto be limited to the exact construction shown and described.

Having thus fully described my invention, what I claim is 1. In aflushing apparatus for water-closets, a lever pivoted to the tank andoperated by the depression of the closet-seat, a rod attached to saidlever and carrying a pivoted gravity trip-lever at its upper end, incombination with a pivoted lever actuated by said trip-lever andconnections for opening a flushing-valve inside the tank.

2. The water tank, the seat lever, the weighted trip-lever, the leveractuated by the trip, the rock-shaft, the cup-valve for flushing thecloset, and a Weight connect-ed to the seat-lever for opening the valve,substantially as described.

3. In a flushing attachment, a hinged seat, a lever actuated by saidseat, a trip operated by said lover, a rock-shaft operated by said trip,a cup-valve suspended from said rockshaft, an overflow-pipe, arefilling-pipe connected to said overflow-pipe, and a valve at the upperend of the refilling-pipe, said valve being controlled by an adjustablefloat, substantially as described.

4. In a flushing apparatus, a hinged seat, a seat-lever having afriction-roller journaled at its outer end and bearing under the seat, arod connected to the long arm of said lever and extending up into thetank, a weight secured to the end of said rod, and a springbuffer .underthe weight, a trip actuated by the seat-lever to close theflushing-valve when the hinged seat is depressed, said weight serving toopen said valve when the seat is raised by the seat-lever, substantiallyas described.

5. A hinged seat, a lever actuated by said seat, two upright rodsconnected to said lever, one of said rods passing up through the bottomof a water-tank into a separated compartment, a weight onthe end of saidrod, a buffer-spring under the weight, the other rod sliding in guidesat the side of the tank and carrying a weighted trip for actuating arock-shaft connected to a flushingvalve, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

WILLIAM H. OSBORN.
